Actor Dean Cain says he can't understand why gay marriage is an issue.

During an appearance on HuffPost Live, the 46-year-old Cain was asked whether playing gay in the 2000 film The Broken Hearts Club: A Romantic Comedy affected him on the issue of marriage equality.

“Me, no,” answered Cain, who is best known for playing the “Man of Steel” on Lois & Clark: The New Adventures of Superman. “Listen, I'm 46 years old. I've never been married. If anybody wants to get married, go ahead. Rock and roll.”

“I understand. I have a lot of gay friends,” he added. “I can't understand why it's an issue. For me, it's a non-issue.”

“But doing the Broken Hearts Club, that was my feeling to begin with. It never has been an issue for me.”

Dean, a registered Republican who reportedly backed Mitt Romney for president last year, will next be seen in the VH1 series Hit The Floor.
